PRIMARY outcome

Timeframe: At the time of cell collection.

Population: 79/348 (Arm 1) and 81/355 (Arm 2) participants were excluded from the sensitivity/specificity analysis due to biopsy (Bx) and/or endocervical curettage (ECC) results not being reported

True Positive (TP); True Negative (TN), False Positive (FP) and False Negative (FN) participants and percentage of participants based upon comparison of the cytology diagnosis (Dx) with biopsy (Bx) and endocervical curretage (ECC) results from the same patient.
